VENTILATOR.

Application filed April 13, 1923. Serial No. 631,785.

To all whom it may conceive:

Be it known that ANDREW BIKER, a citizen of the United. States, andresident of Fairfield, in the county ofFairfield and StateofConnecticut, has invented certain prevent a direct view through theventilatorfrom one side to the other of the door and to prevent thedirect passage of air currents through the closure. V I I A furtherobject is .to provide a ventilator including spaced apart louverscapable of being incorporated in the opening of a door or the like toclose the same without necessity offitting the louvers to said opening.A further object is to provide a ventilator which can be installed inopenings of variable size in doors or the like without altering theelements of the ventilator or fitting them to the door, the constructionof the elements making the ventilatingclosure capable of being installedin an opening: of greater. or less size, within limits as will apiearr 1A still further object is to provide anovel and improved article ofmanufacture of the present character which can be furnished to the tradein two main units to be installed by unskilled workmen, the units beingso constructed as to make it impossible to instal the ventilator for usein any except the way it is intended to be installed. I Another objectis to provide a ventilator consisting of two main units oneof-which canbe arranged upon one side of an opening and the other of which can bearranged upon the opposite side of said opening, and devices forsecuring the units to each other and against the surfaces of a dooror'the like adjacent the opening.

Another object is to provide a ventilator constituted by two units oneof whichconsists of a louver and the other of which consists of a louverwith simple slide, and devices adapted to connect the louvers with eachother and to clamp the louyersagainst oppositely disposed surfacesadjacent an opening in a door or the like without entermg or in any waymarring'the surfaces of the door or the like. v

Anotherobject is to provide a ventilator which can be secured inopenings of doors or the like which vary in thickness, that is, I

in doors having theiroppositely disposed surfaces adjacent theiropenings to be closed arranged at variable distances apart, withoutnecessity for adjustment or alteration ofthe main units of theventilator.

And yet another. object is to provide a I ventilator of the presentcharacter having a simple slotted or apertured slide associated with alouver in novel and improved manner to be'easily manipulated to allowopenings through the ventilator or to close said openings. I V

VVith the above and other objectsin view, the invention comprises theconstruction,

arrangement and combination of, parts as now to be fully described andas hereinafter to be specifically claimed, it being under stood that thedisclosure herein is merely illustrative of the principles of the inven-.tion and meant in no way in a limiting sense, changes in details ofconstruction and arrangement of parts being permissible so long aswithin the scope of the appended claims. I

Inthe accompanying drawing formingla part of this specification,

Fig. l is an elevational view of a door or the like as seen from theinside'of a build ing, showing the improved ventilator applied touse; jV

Fig. 2 is a sectional View on line 2-2in Fig. 1, looking in thedirection of the arrows;

Figs. 3 and 4. are perspective views of the outer and'in'ner louvers ofFigs. 1 and 2, showing the oblique flanges of said louvers extending indifferent direction from the plates or bodies of the louvers;

Fig. 5 is a perspective view of the slotted or apertured. slide to beassociated with one of the louvers of Figs. 3 and 4; and

Fig. 6 is an enlarged fragmentary sectional view on line 66 in Fig. 1.

With respect to the drawing and the charvacters and numerals ofreference indicated thereon, A denotes a door or the like with opening Bto receive a ventilating closure,

and C andD denote,respectively, 'the outer and inner surfacesof saiddoor adjacent the opening B. The ventilator of the present invention isadapted to be clamped against the surfaces and D to serve as a closurefor said opening.

Numerals 10 and ll -denote-louvers adapted to be clamped against thesurfaces C and D, respectively, of the door A, each louver, naturally,being of the general configuration of the opening B, rectangular asshown.

Each louver may consist of a single piece ofmetal suitably shaped forits pun pose, although either or both louvers could be constructeddifferently. That is to say, each louver 10, ll'consists of a desirablyflat, rectangular plate or body 12 having a continuous, desirablyL-shaped margin or doub'le flange 13 comprising a continuous flange 14adapted to lie in opening B when the ventilator is put to use and acontinuous flange 15 adapted to engage a surface C or D as the'case maybe. The margin or double'flange 13 need not be L-shaped, but each"flange 14 should be of uniform width forits full length'in order thatthe plates or bodies 12 of the'louvers 10, 11 will be parallel with eachother, and each flange 15 should be parallel with the p-latesor bodies12 in order that the flanges 15 will lie snugly against the surfaces C,D, as will be understood.

The continuous flanges 15 can be plain or can have any design intendedto enhance the appearance of the ventilating closure.

Each plate or body 12 of the louvers 10, 11' is provided with slots orapertures 16 for the passage of air through the ventilator, and adjacenteach slot or aperture 16 is a preferably obliquely disposed flange 17,all of the flanges 17 extending from the face of eachp'late or body 12opposite the L- shaped margin or double flange 13. As disclosed, theflanges 17 extend nearly the width of the plates or bodies 12 and areconstituted by'metal struck from said plates or bodies 'to produce theslots or apertures 16.

In order that there can be no direct line of vision through the louverswhen the elements of the ventilator are assembled, the slotsor apertures16 of the different louvers are arranged in staggered relation, and allofthe oblique flanges 17 extend toward the same side of the ventilatingclosure, as best shown in Fig. 2 and Figs. 3 and a, the flanges of Fig.2 all extending toward the right of the ventilator and the flanges ofFigs. 3 and .-all being adapted to extend toward the left-when thelouvers are assembled to prod the closure.

Numeral 18- represents a slotted or apertured slide adapted to besuitably associated with one of the louvers. This slide maybe'associated with the inner louver 11 in the following manner: A lowerstrip 19,adja cent the bottom portion of the L-shaped margin 13,preferably extending about the length of the plate or body 12, may be-drawn as at 20 to provide annular flanges 21 adapted to-engage the faceof said plate or body 12 t0 space the lower strip a suiticient-distancefrom the plate or body 12 to allowinsertion ofthelower edge portion ofthe slide 18 between said plate or body and strip, and hollow rivets 22,passing through openings in the annular flanges and through openings 29in theplate or body 12 of the louver 11, may be utilized to secure thelower strip 19 to-said louver 11. SeeFigs. 2 and 6. After the slide isso inserted, an upper strip 19,'adjacent the'upper portion of theL-shaped ma'rgin 13" and extending approximately the length of the plateor body, may be securedto saidplateor body in the exact manner ofsecuring the lower strip toconfine the upper edge portion of the slide.The slide isthus confined in the depression defined by the L-shapedmargin and permanently associated with the louver 11, its sidewisemovements, obviously, being limited by the annular flanges 21 or by theside portions of the:L'-shaped margin. As shown I utilize three-sets of"devices'to hold each strip 19 to louver 11. Evidently, any number ofstrip retaining devices can be employed.

The slide 18 has apertures or slots 23 extending the greater part of thewidth'thereof and arranged to correspond with the apertures orslots inthe'plate' or body 12 of 'the louver 11. A manipulating handle 24,

desirably arranged centrally of the slide, allows for ready adjustmentoftheslide to open'or close the apertures or slots through the louver 11.The upper andlower edges of the slide maybe cut away'as'at 25 (Fig. 5)in order that there will-be no interference by the'strip retainingdevices when the slide is manipulate'dlfrom one side toward the other ofthe ventilating closure.

The louver 10 may constitute a single unit of the ventilator, while thelouver 11 with slide 18, strips'19, and hollow rivets 22 retaining thestrips to. louver 11, may-consti tute another unit, these-beingthe twomain units of the ventilating closure.

Numeral "26 denotes bushings, which may be carried by the louver lO,having threaded openings 27-togreceive screws 28-adapted to pass throughthe hollow rivets 22 to. hold the unitsof the ventilatorto each other,it

being understood that the arrangement of the bushings26 upon the louverl0 corresponds with the arrangement of the'hollow rivets in the louver11.

The two main units constructed as illustrated and described canbe'furnished to the trade. It is apparent that-any unskilled 'workman caninstall the units, placing one of the louvers so that-itscontinuousfflange 15 engages the surface C-of the door A and the otherunit sothatitsflange 15 engagesthe surface 1), with theeontinuousflanges 1 1 and. plates or'bodies '12 lying adjacent each other withinthe opening B. Evidently, no fitting of the units in the opening isrequired, the continuous flanges 14 being capable of being spaced agreater or less distance from the wall of the opening B.

Several different arrangements could be employed for insuring thatworkmen cannot install the ventilator in any except the way it isintended to be installed. As shown, one of the strip retaining devicesincluding a hollow rivet to receive a louver clamping screw (the upperintermediate one) is ofl center, so that there is only one way that theunits can be joined.

When the louver clamping screws 28 are manipulated to draw the louverstoward each other, the continuous flanges 15 of the.

Lshaped margins 13 are drawn against the surfaces C and D of the door Aand the flanges 15 are adapted to lie snugly against said surfaceswithout marring them.

The bushings 26 are adapted to limit the tension which the flanges 15can exert against the surfaces of the door or the like and when theventilating closure is set up the open ends of the bushings arepreferably situated close to (almost contiguous with) the plate or body12 of the louver 11 (see Figs. 2 and 6). When the ventilator is to beinserted in a door having thickness greater or less than that of thedoor illustrated, bushings and screws 28 suitable to the thickness,longer or shorter than those shown, may be utilized.

It is evident that the portion or margin 13 of either or both louvers10, 11 could be of configuration different from that shown and could bea separate piece of material secured to the louver and against a door orthe like in any manner, as, for example, by the screws 28, or either ofthe portions or margins 13 could be omitted. In this latter event,screws (not shown) passing through the portion 13 utilized and enteringthe door or the like could constitute the means for incorporating theventilating closure in the opening ofthe door or the like, and all ofthe units of the ventilator could be assembled before they werefurnished to the trade.

Having thus fully described the invention, what I claim as new anddesire to secure by Letters Patent is:

1. In combination with a structure having an opening and walls adjacentsaid opening, a ventilating closure comprising spaced apart louversadapted to cover said opening, each louver including a plate havingapertures and flanges adjacent said apertures and a double flangeattached to said plate and constituting the margin of each louver,

each double flange comprising a continuous flange adapted to lie in saidopening and a continuous flange adapted to be contiguous with a wall ofsaid structure, an apertured slide associated with one of said louversand arranged within its double flange to open or close the ventilatingapertures of said louver, and means for drawing said louvers toward eachother and against said walls.

2. A ventilating closure comprising spaced apart plates each havingventilating apertures and flanges adjacent said apertures, the aperturesof the different plates being arranged in staggered relation and all ofthe flanges of the different plates extending toward the same edge ofsaid closure to preclude direct vision therethrough, a

double flange about the margin of each plate and adapted to extendbeyond the wall of an opening to be filled, an apertured slide permanently associated with one of said plates,

and means whereby said plates can be drawn toward each other to securesaid closure in said opening.

3. A ventilating closure comprising spaced apart plates each havingventilating openings with oblique flanges, the openings and flanges ofthe different plates being arranged in staggered relation to precludedirect vision through the closure, a flange about the margin of eachplate and extend ing therefrom in a direction opposite that in which theoblique adapted to lie in by said closure, a

flanges extend, said flange an opening tobe covered second flange abouteach of said last mentioned flanges, said second flanges being adaptedto lie adjacent oppositely disposed walls of a structure having saidopening, and means for drawing said marginal flanges of the differentplates toward each other to clamp said second flanges against saidwalls.

4. A ventilating closure as specified in claim 3, wherein an aperturedventilating member is situated within one of said marginal flanges toopen or close the ventilating apertures through said plates.

5. In a ventilating closure, a plate having a marginal flange, spacedapart strips secured to and spaced from said plate, and an adjustablemember situated between said strips and'plate, each strip being spacedfrom said plate by annular flanges integral with said strip and beingheld to said plate by hollow rivets entering said annular flanges andplate.
